JPS6011932Y2 - Traffic blocking pole - Google Patents

Description

[Detailed explanation of the invention] This invention usually buries most of it underground.
This invention relates to a traffic blocking pole that can be fixed in a protruding state above the ground to block the passage of cars and people when necessary.

Conventional traffic prevention poles, which can be buried underground or protruded above the ground and fixed, have a structure with a cap attached to the top of a long cylinder, and are usually quite heavy overall. be.

By the way, with this conventional pole, when the fixing means is released when trying to store it underground from a state where it has been protruded from the ground, the pole falls due to its own weight, but the pole is left to fall due to its own weight. In the end, there was a risk that the cap would collide with the ground, damaging it, or falling onto the operator's feet on the ground, causing injury.

The object of this invention is to provide a traffic blocking pole that eliminates the above-mentioned drawbacks of conventional poles.

Hereinafter, one embodiment of this invention will be explained with reference to the drawings.

FIG. 1 is a partially omitted sectional view of an embodiment of this invention.

The lower half of the board 2, which has a dish-like shape and has a hole 1 in the center, is fixed while being slightly buried in the ground surface.

A substantially ring-shaped elastic body 3 is placed on the substrate 2,
The elastic body 3 is made of elastic rubber, synthetic resin, or the like.

FIG. 3 shows an enlarged view of the vicinity of the elastic body 3.

The inner circumferential surface of the elastic body 3 is formed to have a V-shaped cross section,
A tapered surface 4 is formed.

Then, a ring-shaped upper plate 5 is placed above the elastic body 3, and screws 6 are attached to the substrate 2 from above the upper plate 5 through the elastic body 3.
, 6, . . ., the elastic body 3 and the upper plate 5 are integrally attached to the substrate 2.

An inner cylinder 7 is attached near the inner end of the substrate 2 so as to face downward.

Furthermore, an outer cylinder 8 having a slightly larger diameter than the inner cylinder 7 is attached to the outer periphery of the inner cylinder 7.

The outer cylinder 8 is slightly longer than the inner cylinder 7, and a guide pipe 9 is attached to the lower end of the outer cylinder 8 so as to face downward.

The inner diameter of the guide pipe 9 is made to be approximately the same as the inner diameter of the inner cylinder 7, and there is a slight gap between the lower end of the inner cylinder 7 and the upper end of the guide pipe 9.

A long slide pipe 10 is fitted inside the inner cylinder 7 and the guide pipe 9.

The slide pipe 10 has an outer diameter slightly larger than the diameter near the upper end of the inner circumference of the elastic body 3.

A cap 11 is attached to the upper end of the slide pipe 10, and the cap 11 is slightly larger than the upper plate 5.

A U-shaped handle 12 is attached to the center of the cap 11.

A rotating member 14 is rotatably attached to the inner lower end of the slide pipe 10 by a shaft 13, and a spring 15 is attached to the upper end of the rotating member 14 between it and the inner surface of the slide pipe 10 to prevent rotation. The upper end of the member 14 is biased toward one side.

A hole 16 is formed in the slide pipe 10 at a position opposite to the position where the spring 15 is provided.

The lower end of the rotating member 14 has a spring 1 attached to the upper end.
A locking piece 17 is formed in the same direction as 5.

A hole 18 is formed in the slide pipe 10 at the position where the locking piece 17 is formed.

The locking piece 17 protrudes from the hole 18 and the guide pipe 9
is in contact with the inner surface of

When the structure described above is stored, the slide pipe 10 descends inside the inner tube 7 and the guide pipe 9, and the cap 11 covers the top plate 5, as shown in FIG. When you want to use the slide pipe 10, hold the handle 12 and lift the slide pipe 10.

The slide pipe 10 rises inside the inner cylinder 7 and the guide pipe 9, but at this time, the locking piece 17 of the rotating member 14 rises while contacting the inner surface of the guide pipe 9, and the lower end of the inner cylinder 7 and the guide pipe 9, the locking piece 17 fits into the gap and the slide pipe 10 no longer rises (FIG. 2).

Therefore, even if the handle 12 is released, the locking piece 17 is still attached to the guide pipe 9.
Since it rests on the top edge of the machine, it is prevented from descending, allowing it to remain in use.

Since the inner circumferential surface of the elastic body 3 has a V-shaped shape when viewed in cross section, even though the upper end of the inner circumferential surface is in close contact with the slide pipe 10, when the slide pipe 10 is raised, The frictional force generated between the slide pipe 10 and the elastic body 3 is not so large, and therefore the resistance force when lifting the slide pipe 10 is not so large.

Next, when you want to put it in the stored state, insert the tip of the tool T into the hole 16 of the slide pipe 10 in the state shown in FIG. 2, and push the upper end of the rotating member 14 in the direction of arrow a.

The rotating member 14 compresses the spring 15 while rotating the shaft 13.
The locking piece 17 at the lower end moves backward, detaches from the upper end of the guide pipe 9, and moves into the guide pipe 9.

At this time, the slide pipe 10 becomes capable of descending and begins to descend, but since the inner circumferential surface of the elastic body 3 is shaped like a V when viewed in cross section, when the slide pipe 10 descends, The inner peripheral side of the elastic body 3 acts like a wedge, and the frictional force generated between the slide pipe 10 and the elastic body 3 becomes quite large.

Therefore, the slide pipe 10 does not descend rapidly but slowly descends.

Therefore, the impact generated when the slide pipe 10 descends to the lowest position is small.

As is clear from the above, in the traffic blocking pole according to this invention, the resistance is not particularly large when lifting the slide pipe 10;
0, a fairly large frictional force is generated between the slide pipe 10 and the elastic body 3, and the slide pipe 10 descends slowly, so a large impact will not be generated on the cap when the slide pipe 10 descends to its lowest point. There is no risk of the cap injuring the operator's feet.
